Frequency/volume chart: the basic tool for investigating urinary symptoms.

Abstract

The frequency/volume chart is a simple and inexpensive way of recording basic data, some of which can be obtained in no other way, e.g. total voided volume. The frequency/ volume chart has acceptable reproducibility but limited diagnostic capacity. It provides a basis for instituting treatment in many patients and provides the best tool for following the result of treatment in patients with the urge syndrome.
